femme fatal and encountering timing.

By themcradical1, in Android: Netrunner Rules Questions

im sure someone has asked this before but my question is:

femme says ...when you encounter that ice pay 1 per sub to bypass it... so if you mark lets say a tollbooth. wouldn't you be able to bypass that tollbooth before the ...he or she must pay 3... even activates.

Yes. Bypass is covered in the FAQ.
